pppd no CHAP response when using NM

2012-01-15 Thread Stefan Rutzinger 

Hi,

I'm trying to connect with a GSM USB modem ZTE MF-100 (USB ID 19d2:0039) 
to a mobile broadband network (German Congstar = network of German 
Telecom) with debian testing.


Using KDE NetworkManager, my problem is that pppd doesn't answer the CHAP 
challenge and runs into a timeout (see log file). In NM, the hooks at 
Authentication and at CHAP may be checked or not, doesn't matter. If 
they are set, a hook at EAP always re-appears even when it was 
unchecked.


Using wvdial, the connection is established correctly when stupid mode = 
1 is set.


Maybe this is the root cause but I'm not sure. Is there a way to get more 
debugging (parameters of pppd...) than shown in the logfiles below? How 
can stupid mode = 1 be configured in NM (or any other parameters which 
are not accessible by the GUI of the NM)? Does it read a config file 
similar like wvdial.conf, where is it placed?


According to this page, NM works for others with this provider and this 
HW, so I assume it's not big issue:

Anybody some hints?

backlight control lost after resume - screen black after hibernate

2011-08-19 Thread Stefan Rutzinger 

Hello,

I run Wheezy on a quite new sony vaio PCG laptop with GeForce GT 555M 
(GF106) and a second intel 2D video card and nouveau FB.


After resume from suspend or hibernate, the backlight control gets lost. I 
still can echo and cat to /sys/class/backlight/acpi_video[0,1]/ but it has 
no effect. After a fresh boot, everything behaves as expected and e.g.

FN-Brightness keys work well.

This is especially annoying since at hibernate-resume the backlight is 
switched _off_ and there is no way to switch it back on anymore. It is 
actually off which can be seen when the memory is restored from disk and 
the cursor is blinking in the corner, one can see a slight shine at the 
edges of the display which disapperas immediately after.


The system however is resumed and working, it can be shutdown -r now 
'blind' or be accessed by ssh.


There are a lot of descriptions about the backlight not being restored to 
the correct value but there is nothing about the /sys/../backlight branch 
being without function after resume at all.


Any Ideas?
Stefan

Lost wifi connection

2011-08-19 Thread Stefan Rutzinger 

Hello,

yet another problem. Randomly, my wifi card drops its connection. It seems 
to forget its setting but everything which can be found in the logs is 
shown below. It needs ifdown wlan0; ifup wlan0 to recover.


This seems to be related to the link quality because this occurs more 
often when the signal is poor. However it's annoying having to restart the 
network whenever the signal strength dropped just for a second.

Does anybody know about such a behaviour?
